【００１４】
【発明の実施の形態】
以下、添付図面を参照して説明すると、図示実施の形態は空気を陽極活物質とする空気電池に備えられる電磁誘導型の空気強制供給用アクチュエータ装置として構成されている。その実施の形態は大別すると、図１で示す形態と、図８で示す形態と、図１０で示す形態と、図１１で示す形態とが挙げられている。このうち、図１，図８，図１０で示す形態は磁気回路内蔵型に構成され、図１１で示す形態はダイアフラム内蔵型に構成されている。なお、各形態の共通する構成各部は同じ符号を用いて示す。
【００１５】
その共通形態は、円筒状のハウジング１（１ａ，１ｂ）を基枠とし、マグネット２（２ａ，２ｂ）、ポールピース３，４、ヨーク５（５ａ，５ｂ）から磁気回路を形成し、ボイスコイル６，７をポールピース３，４とヨーク５（５ａ，５ｂ）との磁気ギャップＧに挿置すると共に、間隔を隔てて相対する二つのダイアフラム８，９をハウジング１で張設保持し、ボイスコイル８，９の通電回路を設けることから、反復継続的に振幅動（膨張離間動，近接復帰動）するダブルダイアフラムによる空気ポンプとして構成されている。
【００１６】
図１で示す実施の形態においては、マグネット２として円盤状のものが一つ備えられ、ポールピース３，４は一つのマグネット２を挟んで両側に取付け固定されている。このポールピース３，４を一体に備え、マグネット２はハウジング１の枠内中央に配置されている。ヨーク５としては円筒形の磁性リングが一つ備えられ、各ポールピース３，４と磁気ギャップＧを隔て外側から相対するようハウジング１の枠内に備え付けられている。
【００１７】
そのマグネット２とヨーク５とは、両者の相対間に亘る樹脂製の橋絡プレート１０で一体に連結固定されている。また、ヨーク５はハウジング１との間に亘る樹脂製の支持プレート１１を備え、この支持プレート１１によりヨーク５を含むポールピース３，４と一体のマグネット２がハウジング１の枠内に保持固定されている。
【００１８】
各ダイアフラム８，９は、撓み変形可能な樹脂製薄板状のものとして形成されている。その各面内中央寄りには、ボイスコイル６，７を内面側に取り付けるようリング状の凹陥部８ａ，９ａが設けられている。また、各面内外周寄りには相同期した振幅動を許容する同心円の波打ち部８ｂ，９ｂが伸縮可能に設けられている。
【００１９】
そのダイアフラム８，９は、外周縁をハウジング1の開放端で内周縁に沿って設けられた段部１２ａ，１２ｂにあてがうと共に、嵌込みリング１３ａ，１３ｂで押込み固定することによりハウジング１の枠内で相対するよう気密に張設保持されている。また、各ボイスコイル６，７はダイアフラム８，９より突出させてポールピース３，４とヨーク５との磁気ギャップＧに挿置するよう組み付けられている。
【００２０】
その各部構成では、マグネット２、ポールピース３，４、ヨーク５から磁気回路が形成されている。また、図２で示すようにボイスコイル６，７（符号６のみのみ図示）のリード線６ａ，６ｂをハウジング１の外部に引き出し、ハウジング１の端子台１４に取り付けた端子金具１５ａ，１５ｂと各コイル毎に或いは各コイルの＋，−極を合わせて接続することにより通電回路が設けられている。
【００２１】
その回路構成によっては、各ボイスコイル６，７を介してポールピース３とヨーク５との間、ポールピース４とヨーク５との間が相逆のＮ，Ｓ極を呈する（図１参照）よう回路設計されている。この電磁誘導型アクチュエータの回路構成により、ダイアフラム８，９は相同期して振幅動を反復継続的に行えるよう備え付けられている。
【００２２】
そのアクチュエータ機能を空気ポンプとして応用するべく、図１で示す実施の形態においては、空気の取込み口１６並びに吹出し口１７が枠内外に連通させてハウジング１の側面に設けられている。このうち、空気の取込み口１６に合わせては開閉弁１８がハウジング１の内側に備え付けられている。また、空気の吹出し口１７に合わせては開閉弁１９がハウジング１の外側に備え付けられている。
【００２３】
その空気の取込み口１６は、一つまたは複数個をハウジング１の円周方向定間隔毎に並べて設けられる。空気の吹出し口１７は、空気の吹出し方向に合わせて一つまたは複数個を相隣接させて並べることにより設けられる。この空気の吹出し口１７を一つ設ける場合は、丸穴でも、縦または横に向かう長穴としても設けられる。なお、図２で示すように空気の取込み口１６並びに吹出し口１７と相応させて、空気流路となる切欠１１ａ，１１ｂが支持プレート１１の円周縁に設けられている。
【００２４】
開閉弁１８（１９）は、図３で示すように空気の取込み口１６，空気の吹出し口（１７）よりも広い面積の遮蔽部１８ａを有し、その遮蔽部１８ａの周回りから外方に伸びる複数の支持アーム１８ｂ，１８ｃ…を設けた弁体を備え付けられる。この開閉弁１８（１９）は、各支持アーム１８ｂ，１８ｃ…の突端部をハウジング１の壁面に固定することにより取り付けられる。
【００２５】
その開閉弁１８（１９）の他に、図４で示すように遮蔽部１８ａとの付け根から突端部までが遮蔽部１８ａの円周方向に伸びる支持アーム１８ｂ，１８ｃ…を設けたものも備えられる。この開閉弁１８（１９）では、弁体としてコンパクトなものに形成できて開放時のストロークを大きく設定できる。
【００２６】
このように構成する空気強制供給用アクチュエータ装置では、電流の印加で作動させると、ダイアフラム８，９が相同期して振幅動を反復継続的に行う。そのダイアフラム８，９が膨張方向に振幅するときは、図５で示すように開閉弁１８が開き、開閉弁１９が閉じることにより、空気が取込み口１６からハウジング１の枠内に流入する。
【００２７】
一方、ダイアフラム８，９が近接方向に振幅するときは、図６で示すように開閉弁１８が閉じ、開閉弁１９が開くから、空気が吹出し口１６よりハウジング１の枠外に流出する。このダイアフラム８，９の振幅動が反復継続的に繰り返されることにより空気ポンプとして作動し、その空気の吹出し口１６から空気を空気電池に送り込めば、空気電池は空気を陽極活物質として電気エネルギーを発生できる。
【００２８】
その空気強制供給用アクチュエータ装置は、電磁誘導型アクチュエータとして構成されているため、ファンモータと比べて低コストで構成できる。また、ボールベアリングや含油メタル等の軸受による回転機構を備えないところから、振動や騒音の問題はない。殊に、ダイアフラム８，９を二つ備えて振幅動させるダブルダイアフラム構造により振動の発生を抑えられる。
【００２９】
それに加えて、ダイアフラム８，９を二つ備えても、磁気回路としてはポールピース３，４を両面に組み付けた一つのマグネット２と、各ポールピース３，４と外側から相対する一つのヨーク５とを備えて形成されているため、少ない部品点数で価格的に安価なものに構成できる。
【００３０】
図７で示す実施の形態においては、空気の取込み口１６並びに吹出し口１７が枠内外に連通させてハウジング１の厚み面に設けられている。この形態では、空気の取込み側と吹出し側とをハウジング１の異なる厚み面に設け、また、同じ厚み面に設け、或いは片方をハウジング１の側面に設け、他方をハウジング１の厚み面に設けるよう設計変更できる。
【００３１】
図８並びに図９で示す実施の形態においては、空気の取込み口１６並びに吹出し口１７が各ダイアフラム８，９に分けて面内中央に設けられている。また、空気の取込み口１６に合わせては開閉弁１８がダイアフラム８の内側に備え付けられ、空気の吹出し口１７に合わせては開閉弁１９がダイアフラム９の外側に備え付けられている。その構成各部の他は、上述した実施の形態と同様に構成されている。
【００３２】
この図８並びに図９で示す実施の形態では、単なる円筒状に形成したハウジング１を備え付けられると共に、空気をダイヤフラム８，９から直接出し入れできることにより空気を速やかに供給できる。また、図１並びに図７で示す実施の形態を含めて、空気電池の設置位置や機器本体の設計等に応じ、空気の取込み側並びに空気の吹出し側からいずれかを適宜選択することにより空気電池や機器本体に組み付けられる。
【００３３】
図１０で示す実施の形態においては、ポールピース３，４を片面に組み付けた二つのマグネット２ａ，２ｂを備え、各マグネット２ａ，２ｂを皿状のヨーク５ａ，５ｂとポールピース３，４とで挟み込んで一体に接合することにより、磁気回路がダイアフラム８，９の各ボイスコイル６，７に対応させて個別に形成されている。その構成各部の他は、上述した実施の形態と同様に構成されている。
【００３４】
図１０で示す実施の形態では、磁気回路を各ボイスコイル６，７に個別に作用することから、ダイアフラム８，９を瞬時に大きく振幅動させられるため、空気の供給量を増大できる。
【００３５】
図１１で示す実施の形態においては、二つに分割形成されたハウジング１ａ，１ｂを備え、ボイスコイル６，７を外面側に取り付けた二つのダイアフラム８，９をハウジング１ａ，１ｂの内部に相対させて張設し、ポールピース３，４を片面に組み付けたマグネット２ａ，２ｂと、磁気ギャップＧを隔ててポールピース３，４と各々相対する皿状のヨーク５ａ，５ｂとを各ダイアフラムの外側からハウジング１ａ，１ｂの両側に備え付けることによりダイアフラム８，９の内蔵型として構成されている。
【００３６】
その構成中、ハウジング１ａ，１ｂとしては凹部２０ａ，２０ｂを相対させて内側に設け、また、開口部２１ａ，２１ｂを凹部２０ａ，２０ｂの中央位置に設け、更に、凹部２０ａ，２０ｂの内部に連通する複数の空気穴２３ａ，２３ｂ、２４ａ，２４ｂを設けたものが備え付けられている。
【００３７】
ダイアフラム８，９は、外周縁を凹部２０ａ，２０ｂの内周縁に沿って設けられた段部２５ａ，２５ｂにあてがうと共に、嵌込みリング２６ａ，２６ｂで押込み固定することにより、ハウジング１の凹部２０ａ，２０ｂで相対するよう気密に張設保持されている。また、このダイアフラム８，９は凹部２０ａ，２０ｂの内部に連通する空気穴２３ａ，２３ｂ、２４ａ，２４ｂにより振幅動可能に備え付けられている。
【００３８】
ポールピース３，４を片面に組み付けたマグネット２ａ，２ｂは、マグネット２ａ，２ｂをヨーク５ａ，５ｂの皿内に取付け固定し、そのヨーク５ａ，５ｂを開口部２１ａ，２１ｂの内側に嵌め込むことによりハウジング１ａ，１ｂに夫々取付け固定されている。
【００３９】
この実施の形態においても、各ダイアフラム８，９のボイスコイル６，７をポールピース３，４とヨーク５ａ，５ｂとの磁気ギャップＧに夫々挿置させて磁気回路を形成すると共に、ボイスコイル６，７のリード線（図示せず）をハウジング１ａ，１ｂの外部に引き出し、端子金具（図示せず）と接続することにより通電回路が設けられている。
【００４０】
この実施の形態においては、空気の取込み口１６並びに吹出し口１７をハウジングに設け、その空気の取込み口１６に合わせて開閉弁１８をハウジング１ａの内側に備え付け、また、空気の吹出し口１７に合わせて開閉弁１９をハウジング１ｂの外側に備え付けることにより、上述した実施の形態と同様にダイアフラム８，９の反復継続した振幅動による空気ポンプとして構成されている。
【００４１】
図１１で示す実施の形態では、磁気回路を各ボイスコイル６，７に個別に作用することから、ダイアフラム８，９を瞬時に大きく振幅動させられると共に、ダイアフラム８，９の相対間隔による空間を大きく取れることにより、多くの空気を一度に供給できる。
【００４２】
上述したいずれの実施の形態でも、振動や騒音の問題がなくしかも価格的に安価なものに構成できるため、好適な応用例として空気電池に備え付けられる。この空気電池の場合、空気電池のエネルギー容量をセンサーにより検知し、エネルギー容量が低減した時に、空気強制供給用アクチュエータ装置を空気電池自体で作動させて電気エネルギーを発生させるよう装備できる。
【００４３】
但し、空気電池は好適な応用例であり、その他にも、空気の供給を要するものであれば空気強制供給用として広範な用途に適用できる。
【００４４】

Due to the circuit configuration of this electromagnetic induction type actuator, the diaphragms 8 and 9 are provided so that the amplitude movement can be repeatedly and continuously performed in phase synchronization.
[0022]
In order to apply the actuator function as an air pump, in the embodiment shown in FIG. 1, an air intake port 16 and a blowout port 17 are provided on the side surface of the housing 1 so as to communicate with the inside and outside of the frame.
